Overview
EN 12201-5:2024 (CEN) defines the fitness for purpose requirements for assembled polyethylene (PE) piping systems used to convey water (including drinking water and raw water prior to treatment), drains and sewers under pressure, vacuum sewer systems and other non‑industrial water applications. The part addresses how components perform when joined into a system and the tests and preparation methods required to assess system performance under normal and extreme conditions. It supersedes EN 12201-5:2011 and adds coverage for PE 100-RC materials.
Key topics and technical requirements
- Scope of applicability
- PE pipes, fittings and valves joined into systems with allowable operating pressures (PFA) up to 25 bar and a reference design temperature of 20 °C (see EN 12201‑1:2024 Annex A for constant temperatures >20 °C up to 50 °C).
- Intended uses include sea outfalls, pipes laid in water and pipes suspended beneath bridges. Industrial applications are excluded.
- Jointing methods covered
- Electrofusion, socket fusion, butt fusion and mechanical joints.
- Material compatibility: butt/electrofusion applicable to PE 100, PE 100‑RC, PE 80; PE 40 is limited to mechanical fittings.
- Testing and preparation
- Specifies methods for preparation of test-piece assemblies and the tests to assess fitness for purpose (pressure tests, decohesion/tensile tests, leak/negative pressure tests referenced via ISO/EN test methods).
- Distinguishes procedures and acceptance requirements for normal vs extreme conditions.
- Intended for manufacturer and laboratory assessment of component combinations - not intended for on‑site system testing.
- Performance limits and responsibilities
- The purchaser/specifier is responsible for selecting appropriate pressure classes, colours and any national/regulatory requirements for drinking water contact.
Practical applications
- Design validation and type‑testing of PE piping systems for:
- Drinking water distribution and raw water conveyance
- Pressure sewers, vacuum sewers and other pressurised drainage
- Marine outfalls and suspended pipeline installations
- Use cases include system development, product certification, and pre‑qualification of jointing methods and component compatibility.
Who should use this standard
- PE pipe, fitting and valve manufacturers
- Materials and component testing laboratories
- Product conformity and certification bodies
- System designers, specifiers and purchasers needing to verify system performance and joint integrity
- Standards committees and regulators referencing system-level fitness-for-purpose criteria

Introduction
This document specifies the requirements for a piping system and its components made from
polyethylene (PE). The piping system is intended to be used for water supply intended for human
consumption, including the conveyance of raw water prior to treatment, drains and sewers under
pressure, vacuum sewer systems, and water for other purposes.
In respect of potential adverse effects on the quality of water intended for human consumption, caused
by the product covered by the EN 12201 series:
— this document provides no information as to whether the products may be used without restriction
in any of the Member States of the EU or EFTA;
NOTE Attention is drawn to the presence of national regulations and testing arrangements in relation to
products intended for use in water supply to ensure fitness for contact with drinking water.
Requirements and test methods for components of the piping system are specified in EN 12201-1,
EN 12201-2, EN 12201-3 and EN 12201-4. CEN/TS 12201-7 [1] gives guidance for assessment of
conformity.
This part of EN 12201 covers the characteristics of the fitness for purpose of the system.

It also specifies the test parameters for the test methods referred to in this document.
This document is intended to only be used by the product manufacturer to assess the performance of
components in accordance with EN 12201-2, EN 12201-3, or EN 12201-4 when joined together under
normal and extreme conditions in accordance with this document. It is not intended for on-site testing of
pipe systems.
In conjunction with EN 12201-1, EN 12201-2, EN 12201-3 and EN 12201-4 this document is applicable
to PE pipes, fittings and valves, their joints and joints with components of PE and other materials intended
to be used under the following conditions:
a) allowable operating pressure, PFA, up to 25 bar ;
b) an operating temperature of 20 °C as a reference temperature for design purposes.
NOTE 3 For applications operating at constant temperatures greater than 20 °C up to and including 50 °C, see
EN 12201-1:2024, Annex A.
The EN 12201 series covers a range of allowable operating pressures and gives requirements concerning
colours.
NOTE 4 It is the responsibility of the purchaser or specifier to make the appropriate selections from these
aspects, taking into account their particular requirements and any relevant national guidance or regulations and
installation practices or codes.
